SFH6712 Equivalent & Substitute Parts

Part Overview

The SFH6712 is a logic output optoisolator manufactured by Vishay Semiconductor Opto Division, rated for 5300Vrms isolation voltage with push-pull, totem pole output configuration. This 8-DIP through-hole component operates at 5MBd data rate with 2.5kV/µs common mode transient immunity and is designed for DC input applications requiring high-speed signal isolation.

The SFH6712 is classified as obsolete. Equivalent substitute parts are available from active product lines that maintain compatible electrical and mechanical specifications, enabling direct replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFH6712 are selected based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Package / Case: 8-DIP (0.300", 7.62mm) — mechanical fit and pinout compatibility
• Mounting Type: Through Hole — board assembly compatibility
• Number of Channels: 1 — functional equivalence
• Output Type: Push-Pull, Totem Pole — output stage compatibility
• Current - Output / Channel: 25 mA — load drive capability
• Input Type: DC — signal type compatibility
• Voltage - Supply: 4.5V minimum and 15V maximum overlap — power supply compatibility
• Operating Temperature: -40°C ~ 85°C minimum range — thermal operating window

Secondary Compatibility Criteria:

• Data Rate: 5MBd — signal bandwidth
• Propagation Delay: 300ns maximum — timing performance
• Isolation Voltage: Minimum 3750Vrms (all substitutes meet or exceed this threshold)
• Common Mode Transient Immunity: Minimum 1kV/µs (all substitutes meet or exceed this threshold)

All substitute parts listed maintain compatibility across these parameters. Isolation voltage and CMTI values in substitute parts are lower than the SFH6712 but remain within acceptable ranges for applications not requiring the full 5300Vrms specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Broadcom HCPL Series):

HCPL-2202-000E and HCPL-2202-060E are direct functional equivalents with identical propagation delay (300ns) and data rate (5MBd) specifications. Both are ROHS3 compliant and active products. The -060E variant offers extended supply voltage range (4.5V ~ 20V) compared to the original SFH6712 specification. HCPL-2202-000E is recommended for applications requiring strict RoHS3 compliance documentation.

HCPL-2211-000E and HCPL-2212-000E / HCPL-2212-060E provide enhanced common mode transient immunity (5kV/µs to 10kV/µs) compared to the SFH6712 (2.5kV/µs). These parts maintain identical propagation delay and data rate. HCPL-2212 variants are preferred for applications with higher noise immunity requirements. All variants are ROHS3 compliant and active products.

Secondary Substitutes (Broadcom ACPL Series):

ACPL-4800-000E and ACPL-4800-060E offer significantly higher common mode transient immunity (30kV/µs) and extended operating temperature range (-40°C ~ 100°C). Propagation delay is 350ns, which is 50ns longer than the SFH6712. These parts are suitable for applications where CMTI performance is critical and timing margins accommodate the increased delay. Both are ROHS3 compliant and active products.

Compliance Considerations:

All substitute parts are ROHS3 compliant and REACH unaffected, matching the SFH6712 environmental compliance profile. All substitute parts are active products, ensuring long-term availability and supply chain stability compared to the obsolete SFH6712.

Frequently Asked Questions (FAQ)

Q: Can HCPL-2202 series parts directly replace the SFH6712 in existing PCB designs?

A: Yes. HCPL-2202-000E and HCPL-2202-060E maintain identical package (8-DIP), pinout, propagation delay (300ns), and data rate (5MBd) specifications. No PCB modifications are required. The extended supply voltage range (4.5V ~ 20V) in the -060E variant provides additional design flexibility.

Q: What is the difference between HCPL-2212 and ACPL-4800 series substitutes?

A: HCPL-2212 series provides 5kV/µs to 10kV/µs common mode transient immunity with 300ns propagation delay. ACPL-4800 series provides 30kV/µs CMTI with 350ns propagation delay. Select HCPL-2212 for applications matching the original SFH6712 timing requirements. Select ACPL-4800 for applications requiring maximum noise immunity where 50ns additional delay is acceptable.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (HCPL-2202-000E, HCPL-2202-060E, HCPL-2211-000E, HCPL-2212-000E, HCPL-2212-060E, ACPL-4800-000E, ACPL-4800-060E) are ROHS3 compliant, matching the SFH6712 environmental compliance status.

Q: What is the significance of the -000E and -060E suffixes?

A: The -060E suffix indicates extended supply voltage range (4.5V ~ 20V) compared to standard variants. The -000E suffix represents the standard supply voltage specification. Both variants are functionally equivalent in all other parameters. Select based on your application's power supply requirements.

Q: Can I use ACPL-4800 series if my application requires 300ns propagation delay?

A: No. ACPL-4800 series specifies 350ns maximum propagation delay, which is 50ns longer than the SFH6712 and HCPL-2202 series. Use HCPL-2202 or HCPL-2212 series if your design timing margins require 300ns or faster propagation delay.

Q: Is the lower isolation voltage (3750Vrms) in substitute parts acceptable?

A: Isolation voltage selection depends on your application requirements. All substitute parts provide 3750Vrms isolation, which is lower than the SFH6712 (5300Vrms). If your application requires 5300Vrms isolation, the SFH6712 cannot be substituted. If your application operates at 3750Vrms or lower isolation requirements, all listed substitutes are acceptable.

Q: What is the inventory status of these substitute parts?

A: HCPL-2212-060E (6000 Pcs), HCPL-2212-000E (1468 Pcs), HCPL-2202-060E (5900 Pcs), HCPL-2202-000E (2214 Pcs), HCPL-2211-000E (5695 Pcs), ACPL-4800-000E (5500 Pcs), and ACPL-4800-060E (959 Pcs) are all in stock as new original components. All substitute parts are active products with established supply chains.
